i want set width of red arrow example

you using categories, axis divided evenly between existing categories. in other words, can remove unnecessary categories, example: http://jsfiddle.net/mwqto4n6/

$('#container').highcharts({     xaxis: {          categories: ["2016", "2025"]     },     series: [{         type: 'column',         data: [200, 120]     }] });
